60 seconds = 1 minute
60/15 = 4
12 hops in 15 seconds is the same as
4 * 12 hops in 4 * 15 seconds, or
48 hops in 60 seconds, and since 60 sec = 1 min, it equals
48 hops per minute.
Simple Interest is calculated using the formula: I=P*r*t

r=percentage of interest earned
t= time in years
Answer:
ANSWER: she worked 11 hours at the fast food restaurant and 5 hours helping her aunt
Step-by-step explanation:
First we are going to try to find how many hours she worked on the fast food restaurant so you multiply 4.25 time 16 and x
10.50x + 4.25(16-x) =136.75
10.50x + 68 - 4.25x= 136.75
Then, you subtract 68 from both sides and subtract 4.25x from 10.50x
6.25x=68.75
Divide
X=11 that is how many hours she worked at the FAST FOOD RESTAURANT
Then 16-11 and that gives us how many hours she helped her aunt.
